KEEP ALL YOUR CREDITS AND
GET A BIG SCORE
Play your usual game with one-player mode. When you reach the point where your
opponent usually kills you and the "Finish Him" message flashes up,
press the start button on joypad two, which takes you to the two player mode.
Beat your opponent up on the two player mode and let the timer run down, so that
you'll return to the one player mode. You'll keep all your credits and a big
score.
